CHURN-DASHER.

SPECIFICATION forming part of Letters Patent No. 352,610, dated November16, 1886.

AApplication filed August 26, 1886. Serial No. 211,925. (No model.)

To all whom it may concern:

Be it known 'that I, WILLIAM E. DEPP, a citizen of the United States,residing at Brook'- ville, in the county of Jefferson andv State ofPennsylvania, have invented a new and useful Improvement inGhurn-Dashers, of which the following is a specification.

My invention relates to improvements lin churn-dashers; and it consistsof the peculiar combination and novel construction and arrangement ofthe various parts ,for service, substantially as hereinafter fullydescribed, and particularly pointed out in the claim.

The object of my invention is to provide an improved churn-dasher whichwill violently and thoroughly agitate the cream, an-d thereby accomplishthe operation of churning in a very short time, and to provide a dash'erwhich shall possess superior advantages over all others that havepreceded it in points of simplicity and durability of construction, easeof operation, and cheapness of manufacture.

ln the accompanying drawings, Figure 1 is aside elevation of achurn-flasher embodying my invention, showing it in proper position in achurn,with the latter in section. Fig. 2 is a horizontal sectional Viewon the line xm of Fig. l. Fig. 3 is adetached perspective View of one ofthe inclined dasher-blades with the revolving wheel thereon.

Referring to the drawings, in which like letters of reference denotecorresponding parts in all the figures, A designates the verticaldasher-staft',which is arranged centrally within a suitable vessel andsupported therein, andv this staff is rotated in a vert-ical plane byany suitabledriving-gear; butas this driving mechanism does not form apart of my present improvements I have not deemed it necessary tofurther refer to the same, or illustrate it more fully in thisspecication.

B designates the dasher-blades, which are permanently secured tothevertical staff and project outwardly therefrom. These dasherbladesextend from opposite sides of the ver tical dasher-staff, and in aninclined position with relation thereto, the blades being inclineddownwardly and outwardly from the staff, and having their lower endsprojecting beyond the vertical faces of the staff, and their inner endssecured to the staff at the sides of the latter, as clearly shown.

C designates the revolving wheels, 'which are carried at the lower freeextremities of the inl clined dasher-blades B, one of these wheels beingprovided for each of the inclined dasherblades. These agitator-wheelsconsist of a central hub, c, and a series of inclined wings, c', whichare arranged diagonally to each other and equidistant apart, so that thecream will strike the wings during the rotation of the dasher throughthe cream, and thereby revolve the agitator-wheel, as Will be veryreadily understood. This agitator-wheel has a shaft or pin, d, passingthrough a suitable opening, c, in the central hub thereof-and this pinis rigidly afied to the inclined dasherblade B. The agitator-wheels arearranged on one of the sides of the inclined flasher-blades and at theouter end thereof, and the wings of the agitator-wheel are inclined at agreater angle thanthe inclination of the ldasher-blade, and so arrangedwith relation thereto that the front edge of the said wing clears theend of the blade B in advance of the rear` edge of the wing, whereby thecream that is deflected from the upper inclined surface of the blade Bwill strike the radial diagonal wings of the agitatorwheel, and thusincrease the speed of the said wheel, which is rotated by the wingspassing through the cream during the rotation of the dasher.

This being the construction of my improved upward current of creamgenerated by the re volving inclined blade B, the cream being deflectedfrom the upper surface of the downwardly-inclined blade and impingingwith considerable force upon the diagonal blades of the agitator-wheel.

Although I have only shown and described my improved dasher as beingprovided with eight of the downwardly-inclined blades B, and theloosely-journaled agitator-wheels carvried on the outer extremities ofthe blades,

still I would have it understood that I hold myself at liberty toincrease and vary the number of blades and the agitator-wheels therefor,as may be deemed desirable or be` found to give the best results inpractice.

I do not desire to broadly claim the combination of a verticaldasher-stalf carrying horizontal arms to which are loosely connectedvertical wheels, as Iam aware that such a device is not new; but Iconfine myself to the combination with an inclined dasher-blade rotatingwithfthe Vvertical shaft, and the agitator-wheel loosely journaled onthe outer end of the said inclined blade and having its radial wings setat an angle to the blade, whereby the current of cream that is deflectedfrom the said blade will act upon the wings ofthe agitator-wheel andthereby accelerate the speed thereof.

It will be observed that the Wheels in my churn are arranged parallelwith and on one side of the blades B at the lowest point thereof, withthe win gs ofthe wheels extended above the blades. Inasmuc-h as the edgeof the blades strikes the cream first, the crea'm will be defected downthe blades, (by reason of the downwardincli nation givento the blades,and, striking the wings C' Cof the wheels,will cause the latter torevolve. By this arrangement there is little or no resistance offered bythe wheels against the body of the cream, since the blades will cutthrough the latter, and the wh eels areso disposed as to bereadilyrotated by the creamcurrents descending the blades, and yet oeringlittleresistance to the rotation of'. the dasher.

It will also be observed that the several blades B are disposed indifferent horizontal planes, so that the wheels will not interfere witheach other in their action on the body of the cream.

My improved churn-dasher is very simple and strong of construction,cheap and inexpensive of manufacture, and thoroughly eicient andreliable in operation, t-he4 dasher creating a very violent agitationamong theparticles of the cream, and thereby facilitating the operationof churning.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-

A churn-dasher comprising the rotary shaft A and the downwardly-inclinedblades B, affixed to and extending outward from the staff, the wheelsC,loosely journaled directly to one side of and parallel with the bladesat the lowest point thereof, and wings C', provided on the wheels andextended above the blades,

`whereby the blades will cut through the cream,

and the currents descending or deflected down the blades will strike thewings of the wheels, as set forth.

In testimony that I claim the foregoing as my own I have hereto aflixedmy signature in presence of two witnesses.
